getting the item nav and item header to be site wide

Hello I am trying to custom my theme for buddypress which I am really enjoying and wanting to see if I could get some help or guidance.
I would like to display the item nav and item header to be site wide for logged in users. I have got the code below from the members/single/home.php and it well work for when I am on the members pages but every where else like on /activity or /groups or /members it just doesn’t display any user information. What could i I do to display the current logged in users information?
